HAMMER.

. To all whom it may concern: I

Be it known that I, MICHELANGELO FER- RARO, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and usefulImprovements 1n Hammers,

of which the following is a specification.

The object of this invention is to provide a hammer, hatchet or other striking implement with a clip which will prevent its head from coming off and to construct said clip so that it will be simple and inexpensive to manufacture and readily. attachable to and detachable from the implement and so that it will protect against injury the end of the wooden handle of the implement where it penetrates the head and is thereby exposed.

In the drawing. Figure 1 is a side view, partly in section,

. of a hammer embodymg my invention;

Fig. 2 is a head-end view of the implement;

Fig. 3 is'a section on line 3--3, Fig. 1;

Fig. 4 is an enlarged fragmentary'view of the handle and head and the cap, the latter being detached; and

Fig. 5 shows a modified form of the cap.

The woodenhandle a of the implement is fitted into the socket b of the head 0 of the implement in the usual way, the head being prevented from movement inward on the andle in anyway, as by a shoulder d formed on the latter.

The stub e of the handle over which the head is fitted protrudes outwardly somewhat beyond the handle, as illustrated best in Figs. 3 and 4; this is not indispensable, but

it 1s desirable in order to avoid recessing the outer face ofthe head 0 in order to receive 111 means to protect the head from coming 0 the handle. The protruding end of the stub c has grooves f formed opposite each other and transversely of and in the side or broader faces of said stub; these grooves afl'ord shoulders g facing the head 0 and against which my aforesaid means is to obtain abutment. The cap forming my aforesaid means in Figs. 1 to 4 is formed of an oblong piece it of stiff sheet metal having integral rectangular Wings 71 at its four sides and each of thesame length as the corresponding side, said wings being bent up into perpendicular relation to the piece h so that an oblong box-like structure results closed a at all sides excepting the side opposite the specification of Letters Patent.

piece h. The two long sides have rebent foldsj formedtherein, the same extending inwardly and forming inwardly projecting flanges substantially parallel with the piece or wall h; the outer edges of these sides preferably extend somewhat beyond the .sides of the box-like structure or cap, as

indicated at 76. The two short sides 2' have thelr outer portions bent outwardly, as indicated at Z, and lying in the same plane as the edge portions it" of the long sides. (Com- 7 pare Figs. 3 and 4). When the cap is first formed it will preferably have one short side i left extended, or in the same plane as the wall h (Fig. 4:).

Having assembled the head and handle, which will bring the rear side of the grooves f flush with the outer face of the head 0, the cap is applied to the stub by sliding it thereon transversely thereof and in such manner that its flanges j enter the grooves f of the stub, upon which the side i of the cap left extended as in Fig. 4. is bent into perpendicular relation to the wall it as shown in Figs. 1 and 2.

It will be well to form extensions or ears m on the ends of two opposite sides'i which can be bent so as to overlap the other two sides and thus give strength and rigidity to the cap; in Fig. 5 these ears m are formed on the longer sides 71 but in Figs 1 to 4: they are formed on the shorter sides, the latter being the preferable construction because the ears will then reinforce the longer sides against spreading and the flanges j conse quently against working out of the grooves 7.

It will be seen that the clip extends over the outer end of the handle and thus affords protection thereto, besides beingan inexpensive, simple and readily attached and detached means for preventing the head from coming off.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, with the members to be interlocked and one of which penetrates -the displacement of said other member toward said end and having an inward rebent fold bearing against said shoulder.

2. In combinatlon, with the members to be interlocked and one of which penetrates and protrudes from the other and has on its protruding portion a shoulder facing to Ward the other member, a sheet-metal clip capping the protruding end of the first member and forming an abutment limiting the displacement of said other member toward said end and having four rectangularly arranged side Walls, one of said side Walls having an inbent portion bearing against said shoulder and each side Wall next adjoining the first-named side Wall having ears outwardly overlappingthe latter wall and the side Wall opposed thereto.

In testimony whereof I affix my signature.
